Specification of Letters Patent.

Patented Dec. 8. 1914.

Application filed January 29, 1910. Serial No. 540,793.

- ()gontz, Montgomery county, Pennsylvania,

have invented certain Improvements in Knitting-Wiachines, of which the following is a specification.

lily invention consists of certain ifilprovemerits especially cesigned for use in connection with the knitting machine for which Letters Patent No. 8341,? were granted to Robert ll". Scott on the thirtieth day of October, 1906, although not limited to such application, the objects of my present invention being to permit of the production of a closely knitted ribbed web and to prevent the web holders from interfering with the operation of the machine when ribbed Web is being knitted thereupon. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a view, partly in vertical section and partly in elevation, of suilicient of a knitting machine of the type shown in said patent to illustrate my present invention, the parts occupying the position which they assume when ribbed web is being knitted; Fig. 2 is a similar view illustrating the parts in the position assumed by them when the ribbing needles are out of action and plain web is being produced; Fig. 3 is a plan or top view of the web holders and devices for operating the same; Fig. 4 is a horizontal sectional view with the top of the web holder cam ring removed; Fig. 5 is a view partly in elevation and partly in vertical section on the line n w, Fig. 3; Fig. 6 is a view partly in elevation and partly in transverse vertical section, on the line 25-4), Fig. 3: Fig. 7 is a plan or top view of part of the needle cylinder, and Fig. 8 is a side elevation. illustrating certain operative partsof the machine not shown in the other views.

In the drawing. 1 represents part of the needle cylinder of the, machine, 2 the dial. the cylinder needles, 7 the dial needles, and 3 a shaft carrying said dial and extent ing upwardly to the hub of a spur wheel (Fig. 8) to which it is secured, said spur wheel being driven in consonance with *h mechanism which imparts rotating mo" ment to the cylinder of the machine as fully D set forth in said former patent.

The shanks of the dial needles are pivotally mounted upon a ring carried by the shaft 3 and their upper ends are guided in a ring (3 which also rotates with the shaft, the shanks of the needles projecting above this ring and being acted upon by cams in a non-rotating cam ring 7, certain of these cams having stems 9 which. are raised and lowered by engagementwith the grooved rings 10 connected by rods 11 to a ring 12, the latter being interposed between the hub .05 the spur Wheel 4 and a ring 13, which has one or more cams 14; adapted to beveled recesses in the cross bar 15 or" the fixed frame of the machine, whereby, when said ring 13 is partially rotated, the spur wheel *l and consequently the shaft 3 and all the parts carried thereby may be raised or lowcred, similar raising and lowering movement being imparted to the vertically mowable cams of the cam ring by reason of the connections before described.-

During the production of the plain work upon the cylinder needles web holders 16 cooperate with saidncedles to retain the knitted web, these web holders also operating as sinker-s over which the knitting yarn is drawn by the needles as they descend to knock over the old and draw the new stitches. During rib knitting, however, the web is taken up by a weighted take-up de vice having hooks .c which engage said web, when eXpandcd, as shown in Fig. 1, these hooks being, however, retracted ,as shown in Fig. 2, so as to be free fromengagement with the web, or being otherwise rendered inoperative as a take-up when plain web is being produced. fully described 920,671, granted to Robert ll". Scott and Harry Swinglehurst, on the fourth day 0t May, 1909.

When a closely knitted ribbed web is to be produced, it is advisable to adjust the dial 2 as close to the top of the cylinder 1 as is possible, consistent with the passage of the ribbed web between them, in which position thedial is liable to interfere with the proper operation of the web holders. I therefore provide for the retraction of said web holders and the maintenance of the same in the retracted position during the time that the machine is operating to produce ribbed web, as shown in Fig. 1, the

Such a take-up device is. in Letters Patent No.

gh 1 have shown my invention as to a machine n which are employed swinging i'i' ing needles cooperatw ilisl it can be used in connection with any form of knitting machine intended for the proouction of plain and ribbed web alternate-l3, and in which the ribbing needles and their carrier when in position to cooperate with the plain web needles would interfere with the proper operation of the web holders, or in which it is, for other reasons, advisable to render the web holders inoperative during the production of ribbed web. in the broad embodiment of my invention also, it is immaterial whether the member to which vertical movement is imparted. is that carrying the dial needles, and their cooperating parts, or the cylinder and the parts cooperating therewith.
